Twilio makes it simple to build IVR, or Interactive Voice Response, into your business's contact center. IVR allows incoming voice dialers to navigate a phone menu to pull down the right information, perform automatic transactions and lookups, and find the right person to help. Supplement your human operators or bypass them completely for common transactions and information requests.
By combining decoded DTMF tones with some simple web application logic, you'll be building your call center's menu in no time. Here we've gathered snippets, tutorials, guides, and full sample applications for various IVR use cases across many web languages and frameworks.
The most common IVR use case is to build a simple navigation menu for incoming callers. For common cases, this should get your customers - and potential customers - to the right department. These tutorials show how to use the TwiML <Gather> verb with common web languages and frameworks to create a phone tree.
- Node.js and Express.js
- Python and Flask
- Ruby on Rails
- C# and ASP.NET MVC
- Java Servlets
- PHP and Laravel
It's simple to add voicemail supporIVR: Screening & Recording with Ruby and Railst to your contact center when the call center's closed or a customer needs a callback. These sample applications use the TwiML <Record> Verb then automatically transcribe calls to text for your agents (and salespeople) to better route or handle.
Your particular IVR setup will be unique to your business, but you can tie-in a lot of prior art and best practices from our sample applications and customer examples. We also give you the freedom you need to include your IVR and routing logic into Salesforce or your CRM.
